Extended Mapping

As part of Extended Mapping, which is dependent of the subsystem, several data points are required for object display and operation. This requires that the logical mapping in the system be hierarchical. For example, a pump with digital I/O.

Example 3 shows Pump1 and Pump2 with the PumpFctDigital Function as well as two subordinate data points, Cmd and Dp (no Function assigned). During operation in the Operation tab, the properties of the Cmd and Dp data points are displayed together for the selected pump. During graphic engineering, drag-and-drop takes place on the object hierarchy of Pump1 and Pump2.

Example 4 represents an additional hierarchy between the PumpFctDigital Function and the Cmd and Dp data points. The data cannot be mapped due to different object hierarchies. If both variants exist in a project, the two Functions must be assigned different names (not recommended).

Example 3 shows how a PumpFctDigital Function is created and the .Cmd and .Dp hierarchy information is used for the subordinate objects.

Example 4 shows how a PumpFctDigital Function is created and the Hierarchie.Cmd and Hierarchie.Dp hierarchy information is used for the subordinate objects.

Assigning a Function to an Object (Instance)

With third-party integration, the Function information is not available and must retroactively be assigned manually to the parent object (Pump1 and Pump2) in the Object Configurator (Assigning a Function to an Object).
